I am trying to work out a volume using the cutnfill extension. The area has to be a SOLID to do that and every time that I check the geometry using the brilliant Solid Inspector2 extension it highlights all around the space as having surface border issues.
I have been through the forums and to be honest the definition of what a surface border issue is just doesn’t make sense to me. Can anybody explain it in a way that is meaningful and how do I put it right?
Why are the edges of the space picked up. I know it has no depth at this stage but surely the edge must be a special case???
Secondly how accurate is the volume calculation in Sketchup? I have a before and after model that I have eventually created as a solid by extending the base using the Vector joint push pull extension and then clearing down all the issues highlighted by Solid Inspector2. It has taken three days of work even though I have only used the sandbox tools to create the changes in the first place. I am amazed that sooooo many gaps are created even when the edges of the hidden geometry are selected! . The after has the area built up by almost 0.5m over an area of 3,400m with some levelling of the humps. However according to Sketchup Entity information there is only a 4 cubic metre difference in volume which doesn’t seem right.
Does anybody have experience of using the cutnfill extension before I fork out £20 on it???
As always your help and patience is greatly appreciated.
